Abstract:	One of the possible solutions to minimise the multipath effect in a GNSS (Global Navigation Satellite System) performance consists in introducing a spatial filtering of incoming signals at a GNSS receiver by use of an adaptive antenna array. Development of adequate adaptive array techniques requires a radio channel model that is able to reproduce directional properties of the incoming signals. That information cannot be provided by common single-antenna stochastic channel models; which gives rise to development of specific directional models. This paper presents an approach to simulation of the GNSS directional channel based on the combination of physical and statistical methods of modeling, being the key feature of the model the use of synthetic environments to represent general properties of urban environments. Due to that combination of the methods, the derived channel model preserves the speed and generality of stochastic models and allows obtaining the directional signal information by an intuitively understandable way.
